What Does a Mechanical Engineer Do?

Mechanical engineers are typically involved with the generation, distribution, and use of energy; the processing of materials; the control and automation of manufacturing systems; the design and development of machines; and the solutions to environmental problems.
Research, testing manufacturing, operations, marketing, and administration are some other key activities associated with practicing Mechanical Engineers.
Mechanical engineers are characterized by personal creativity, breadth of knowledge, and versatility. They are also valuable and reliable multidisciplinary team members.
The technical subject areas that form the main basis for their work include mechanics, energy transfer and conversion, design and manufacturing, and the engineering sciences. Through clever use of analysis, modeling, design, and synthesis, they solve important problems to improve quality of life.
Mechanical engineers work on teams responsible for developing a wide range of products and systems including, for example, space shuttle vehicles, aircraft of all sizes and shapes, automobiles, turbines, pumps, power plants, and factories.
Virtually any machine or process you can think of has benefited from the influence of a mechanical engineer.
Everyday conveniences such as refrigeration, microwave cooking, high-fidelity sound reproduction, transportation, communication, and copying are affordable largely because mechanical and other engineers worked together to make it happen.
Mechanical engineers are in demand now, and projections for the future suggest a long-term need for professionals in this specialty. About 20% of the nearly 3 million engineers in the United States are mechanical engineers.
